What is the Preferences > General > Image Interpolation setting?
Could you please post screenshots taken at View > 100% and with the pertinent Panels (Layers, Channels, Options Bar, …) visible to illustrate the issue?
Your terminology seems confusing; technically any Photoshop RGB image is a bitmap image but in Photoshop terminology »bitmap« also refers to 1-bit bitmap (Image > Mode > Bitmap).
I suppose that is the heritage of some decision in the early days of Photoshop …
I convert to smart object first, always, very annoying as it's many 100s of extra steps during working on something
I have assigned F1 to Convert to Smart Object – it is that important a Photoshop operation in my opinion.
Another point: One can set the interpolation method for a Transformation of plain pixel layers in the Options Bar – see if it’s set to Nearest Neighbor.
Hi, thanks for the reply, here's some screenshots showing the difference method, simply copied an area, pasted, then transform, rotate. Looks unfinished and more pixelated.
Then creating a smart object instead. After completing looks smoother.
Preferences > General > Image Interpolation is set to Bicubic (best for smooth gradients) and also tried all of the others, no real change unless I use smart filter.
001 start with a vertical white line
002 Select then transform, rotate
003 Looks more pixellated
004 - go back, instead convert to Smart object first
005- now rotate again
006- looks much better after completing rotation
Thanks c.pfaffenbichler yes sorry I just meant I wasn't using any other special tools, or shapes etc.
I tried all those settings doesn't make much difference to the issue. I just went through them all again and it doesn't help.
"I have assigned F1 to Convert to Smart Object – it is that important a Photoshop operation in my opinion"
Good idea thanks.
You clipped the Options Bar from the screenshots, so it’s impossible to tell the Interpolation setting of the plain Layer’s Transformation.
Where is the options bar?
Yes I apply by pressing enter at the end to stop the transform.
OK yes sorry that is set on Nearest Neighbour there, I had it set in preferences not on the options bar. I just tried on each of the others, and it's better on bicubic. I think that's it thank you!
